Study Summary
Despite decades of research, the mortality in acute lung injury remains very high and treatment options are very limited. Given these facts, the best treatment modality may be in prevention of this lethal syndrome. Historically, imaging has played a crucial role in understanding ALI. The appearance of chest radiography is one of the consensus criteria in defining ALI, and commuted tomography (CT) scans further advanced the understanding of the pathoanatomy of ALI. While valuable, these imaging modalities are nonspecific and do not incorporate functional cellular physiology. PET imaging measures concentrations of radioisotopes in the body. By embedding in, but not altering molecules, the natural fate of these tracers can be studied with PET imaging. Advances in the understanding of ALI include blood flow distribution, as well as the response to alveolar recruitment maneuvers and prone positioning. Not all patients who are receiving mechanical ventilation develop ALI. Inflammation in the lungs is known to play a key early role in the development and progression of ALI. Secondary to inflammation, the lungs develop edema and do not exchange oxygen as well. This early inflammation is in part driven by a specific type of immune cell called the neutrophil. These cells seem to travel and become sequestered in the lung- they are "recruited" to the lung during this inflammatory stage. When there, these neutrophils release inflammatory substances which are integral in the development of ALI. Neutrophils use primarily glucose as a fuel source. The radio isotope \[18F\]Fluorodeoxyglucose (FDG)is a glucose analog and therefore taken up/ingested by the neutrophils as a part of their normal metabolism. Because of this fact, positron emission tomography (PET) using the radio isotope \[18F\]FDG is a highly sensitive marker to look at the recruitment of neutrophils to the lung, therefore quantifying the degree of pulmonary inflammation prior to the development of ALI.
